I think one time I got locked out of the office and was sitting in the parking lot and she never saw me... I had to sit at the door until the next patient let me in... I sat on the couch and waited patiently... She was surprised and we both apologized and I finally got the lock combination so I could come in and be on time.... sometimes we make mistakes...he may have fallen asleep...they forget things....they mess up...they get burned out and need a vacation... he forgot to put it on the calendar.... Who knows what happened? At least you can find out the mystery later... just practice some calmness techniques if you can... I end up using apps on my phone and using biofeedback on my tense body... I don't know your techniques.... just wanted to let you know that I have been through this before and it's ok...not everyone has a vampire Slayer movie with unicorns in the parking lot...try to laugh at it
